Battery vulcanization – Semco University

Introduction Electric car often has the fault two: motor spinning when stopped (battery vulcanization):1. The battery voltage in the state of under-voltage critical will appear when turning and stopping,2. Poor contact with the battery connector will also occur this fault,3. The speed control turns the line to break the state and the brake power off switch is faulty. Battery …

In addition to the capacity, how many other signs on the battery do you know?

Introduction The capacity of the battery refers to the electrical energy that the battery can store in Ah. It has nothing to do with the voltage of the battery. For example, the lead-acid battery is only related to the plate area. The larger the plate area, the larger the capacity. The voltage of the battery …
